Multi-injection Steam Reactor for Uniform Heat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional organic waste processing reactors face inefficiencies due to non-uniform heat transfer from steam to the waste, requiring stirring to distribute heat evenly, which prolongs the decomposition process and decreases reaction efficiency.
Innovation Solution
The reactor design incorporates multiple steam supply pipes with holes arranged vertically, horizontally, and radially within the reaction vessel, allowing for multi-injection of steam to uniformly distribute heat across the waste, enhancing heat transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If steam is supplied to the upper portion of the reaction vessel only, then the steam supply structure is simple, but heat transfer uniformity deteriorates and processing efficiency decreases
Solution Approach 1:
The steam supply system is segmented into multiple injection points distributed throughout the reaction vessel (upper, middle, and lower portions), allowing steam to be injected at various locations simultaneously. This segmentation enables uniform heat distribution across the organic waste without requiring complex external piping systems.
Solution Approach 2:
Different regions of the reaction vessel receive steam injection tailored to their specific heating needs. The multi-point injection system provides localized heat supply where needed, ensuring each region of the waste receives appropriate thermal energy for uniform decomposition.
2Stability of the object's composition
If a stirrer is used to distribute steam throughout the waste, then heat transfer uniformity improves, but the processing time increases and reaction efficiency decreases
Solution Approach 1:
Steam is pre-distributed to multiple locations within the reaction vessel before the decomposition process begins. By establishing uniform heat distribution in advance through multi-point injection, the system eliminates the need for prolonged stirring during the reaction, thereby reducing processing time while maintaining heat uniformity.
Solution Approach 2:
The mechanical stirring system is replaced with a thermal field distribution system that uses multiple steam injection points. Instead of relying on mechanical agitation to distribute heat, the system uses strategically positioned steam injection to create uniform thermal conditions passively, eliminating the time-consuming stirring step.
3Productivity
If multiple steam supply pipes with holes are installed throughout the reaction vessel, then heat transfer uniformity and processing efficiency improve, but device complexity increases
Solution Approach 1:
The steam supply system uses a nested structure where multiple steam supply pipes are arranged concentrically or in hierarchical patterns within the reaction vessel. This nesting allows efficient space utilization and uniform steam distribution while minimizing the overall structural footprint and complexity.

AI summary
A reactor for processing organic waste includes a steam supply pipe installed in a reaction vessel such that steam supplied from an external steam supply device can be supplied into the inside of the reaction vessel. The steam supply pipe has a plurality of steam supply holes so as to supply the steam supplied from the steam supply device to the waste in the reaction vessel through the holes. An organic waste processing apparatus comprising the reactor having the configuration above is provided. Heat due to the steam supplied to the reactor is uniformly supplied to the waste in the reactor within a short time, and thereby increasing processing efficiency.
